sIGNAL MnANs sea Recent-swam coM'rosrNe MACHINES.

Application 'filed. November Washington, in the District of Columbia,

have, invented certain new and useful In'rprovements in Signal Means for Record- Strip Composing Machines, of which the fol-- lowing is a specification. i

My invention relates to signal means for use in connection with a record strip composing machine, for advising the operator when a line, or section or sections of a line are nearing completion.

An mportant ob ect of the invention 1S to provide a device of the above mentioned character, which is in the nature of an attachment, and adapted to be installed upon, or used in connection with the record strip composing machine of the type shown in Letters Patent No. 944,405, issued to J. S.

December 28, 1 909. I Aiurther object of the invention is to provide a device of the above mentioned Bancroft and M. C. lndahl-, under date of character, which maybe used in connection with the record strip. composing machine, of the character stated, w1thout materially altcringthe constructionof the machine.

is is well known, the use of the record strip composing machine, comm-only known as the monotype machine, such asiis shown in Patent No. 944,405, when the line is nearing completion, and the pointer is nearing thcend of the scale, a pincarried by the r em rack, engages and trips a lever, whereby a bellis sounded, and a light is made to glow in the justification cylinder on scale, thus apprising the operator that the end of the line is being approached. I

While this signal meansis t c nsiderable aid to the operator, yet there are disadvantages encountered in connection with the same. The signal is not" adjustable and hence the signal is fixed witli rcspectvto line of a given length. Further, it is custonlary in the operation of these record strip composingmachines to set in one line or row a plurality, such as three, line sections, in-

cluded in three vertical'columns. The operator must watch the pointer andscale, .h aving marked upon the scale the end of the respectiveline sectionsor columns, in order that he may retain the edges of the column straight. In the absence of any signaling means at the end of the line sections or columns, it frequently ha ppel'is that the columns 7, 1922. Serial No. 599,613.

will not be properly straight, at the edge thereof, the signal not being operated until the end of the line, at the edge of the last column. i

In accordance with my invention it pro= vide adjustable means embodying trips which may beset into the active position, at

of each line section or column is approached,

and these signals are auxiliary to the usual signal of the machine, and in no way interfere'with the operation of the usual signal. Further, the trip elements carried by the em rack are adjustable, and hence the device is flexible so that the signals will be properly given, in connection with line. sections or columns of varying lengths.

I also contemplate the provision of an attachment which is adjustable, to operate a signal at the end of a line, line section, or column, which may var-yin length. This attachment may be applied to the record type composing machine of Patent No. 944,405

without materially altering the construc t1on of the same.

part o lithis specification, and in which like numerals are employed to designate like parts throughout the same.

Figure 1 is a perspective view oi the attachment,embodying my invention, showing the same in use.

Figure 2 is a side elevation of the swingv ing tripped member,

Figure '3 is a transverse section through the em rack, showing a modified form of adjustable trip, and,

Figure 4 is a similar v1ew showing a still different form of adjustable trip.

Attention being called first to Figures 1 to 4 inclusive, the numeral 10 (14) desig- I nates the em rack or line scale rack, operating within the guide 11. This guide carries the line scale 12, with the pointer 13 traveling in proximity of the line scale. The nu meral 14E (7) designates the unlts wheel, which advances the em rack 10. The numeral 15 is a vertical stationary rod. 16 (101) designates the latch or lever which trips or actuates the signal means. In the claims, this element will be referred to as the signal actuating means. It is intended that this term cover any means of operating an audible or visual signal or both. As shown in Patent No. 94 1, 105, Figure 28, the lever 16 (101) operates the means to rmg a bell. Thes elements are all old and well known in the art, and are identical with those shown in Patent No. 9 14, 105, to which reference may be had to a disclosure of the complete machine.

In accordance with my invention I provide a stationary bracket 16, having a slotted foot 17, to engage about the rod 15, and clamped thereto by nut or nuts 18 or the like. At its upper end, this bracket carries a forwardly projecting horizontal shaft 19, rigidly secured thereto. Freely pivoted upon the forward end of the shaft 19 1s a forked trip member 20, held agamst lateral displacement by nuts 21 and 22, or by any other suitable means. The swinging movement of the member to the right, is limited by an adjustable stop 20, apertured to receive the shaft 19, and clamped between the nuts 22. The member 20 is provided with depending fingers 23 and 24. which are spaced, and are disposed upon opposite sides of the em rack 10, as shown. These fingers preferably taper downwardly, as shown. The finger 24: is arranged in advance of the latch or lever 16, to engage therewith, and swing this latch upon its pivot.

The finger 23 is arranged upon the forward side of the em rack 10 outwardly of the path of travel of trips 25, when these trips are in the inner inactive position. In Figures 1 and 2, these trips are shown in the form of screws, for their ready adjust ment. The screws are equidistantly spaced, and their distance apart may vary, as may be found advantageous. The selected screws are unscrewed sufficiently, so that they will project forwardly in the path of travel of the linger 23, and hence trip the member 20. If a line is being set, in three sections or columns, three of the selected screws will be adjusted outwardly, so that the member 20' will be actuated as the completion of the line section or column is neared, and hence a signal will be given at this time.

Instead of providing the screw-threaded openings 26 and the screws 25, these elements may be dispensed with, and I may provide the forward side of the em rack 10 with a longitudinal groove 27, trapezoidal in cross section. This groove may extend from the leading end of the em rack to the pointer 13. I then provide any suitable number of trips 28, having trapezoidal heads 29, slidable in the groove 27. The trip 29 carries a nut 30 screw-threaded upon its outer end, and a coil spring 31 surrounds the trip and engages between the nut 30 and the forward face of the em rack. The spring 31 provides suflicient frictional engagement between the head 29 and the groove 27, whereby the trip will be held in the selected position, upon the em rack, when shifted thereto. If a line is being set in three sections or colun'ms, three of the trips 23 would be employed, properly adjusted upon the em rack, at the points near the con'ipletion of each line section or colun'm.

In Figure l; I have shown a further modification of trip. The numeral 32 designates the trip, provided at its rear or inner end with diverging resilient ears 33, fitting within the groove 27, and adapted to frictionally engage with the side walls of the groove, to hold the trip 32 in place within the groove, when adjusted therein, to a selected position.

In view of the foregoing description, it is thought that the operation and use of the forms of the invention, should be readily understood, and that no further description, is deemed necessary.

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same, and that various changes in the shape, size, and arrangement of parts may be resorted to without departing from the spirit of my invention, or the scope of the subjoincd claims.

Having thus described my invention, I claim:

1. The combination with the longitudinally moving em rack of a record. strip composing machine, of a plurality of adjustable trips arranged upon said rack, a movable member having a part thereof arranged in the path of travel of said trips, and a signal actuating element operated by said. movable member.

2. The combination with the longitudinally moving em rack of a record strip composing machine, of a signal actuating element arranged upon the rear side of said rack, a plurality of trips adj ustably mounted. upon the forward side of said rack and adapted to assume proper spaced positions, and a movable member having a part thereof extending upon the forward side of said rack to engage with said trips and also having a part extending upon the rear side of said rack to engage with the signal actuating element.

3. The combination with the longitudinally nlOving em rack of a record strip com- Jun rack, a stationary support, a rod carried by the support and projecting forwardly over sald rack, a member pivoted upon SIlCl rod above the rack and having its loWer end forked to provlde spaced lingers d1sposed upon opposite sides of said rack, one finger being arranged to engage the pivoted lever, and a plurality of trips carried by the opposite side of the rack.

4. The combination With the longitudinally moving em rack ofa recordstrip o0mposing machine, of a movable signal actuating element arranged upon one side of said rack, said rack being provided upon its opposite side with a plurality of spaced screwthreaded openings, a corresponding number of stops having parts thereof screwihreadcd into said screw-threaded openings and adapted to be adjusted laterally With relation to said rack, and a pivoted member having a finger arranged to coact With said stops and another finger to actuate said signal actuating element. v

In testimony whereof I affix my signature.

STEPHEN HARDER.
